Abstract: A liquid curing apparatus for a liquid transfer device includes a liquid transfer unit and a plurality of ultraviolet-emitting diodes. The liquid transfer unit transfers an ultraviolet curing liquid to a transfer target body. The plurality of ultraviolet-emitting diodes are arranged to oppose the transfer target body and emit only ultraviolet-wavelength light to irradiate the transfer target body to which the liquid has been transferred by the liquid transfer unit, thereby curing the transferred liquid.

Abstract: An apparatus for mounting a plate on a plate cylinder includes a plate lockup device, a reference pin, a detecting sensor, and a lamp. The plate lockup device is provided in a gap formed in a circumferential surface of the plate cylinder. The reference pin is supported by a gripper portion of the plate lockup device and engaged with a reference pin hole formed at an insertion end of a plate when the plate is inserted into the gripper portion of the plate lockup device. The detecting sensor is arranged at a position corresponding to at least a bottom portion of the reference pin hole to electrically detect that the bottom portion of the reference pin hole contacts the reference pin. The lamp confirms and indicates insertion of the plate on the basis of an output from the detecting sensor.
